I agree that the proposal is silly, but so are the comparisons between elevated highways/rails and a gondola. The chasm between the elevated highways/rails and cable car in terms of visual and audible impact to the immediate area is immense.

I also don't fault Millennium for proposing something as silly as this. 100M could potentially fund the entire project. 100m to the MBTA to improve SL service doesn't guarantee that any work will be done. This obviously won't happen, but it's not the worst idea/strategy ever to push for improved transit to the Seaport since nothing else seems to be happening.
